CENTRIFUGAL OILER.`

SPECIFICATION forming 'part of Letters `Patent No. 288,667, dated November 20, 1883.

' W Application `filed September s, 1833. (No model.) i

To all whom it may concern Be it known that I, GEORGE B. Ross, a citizen of the United States, residing in Buffalo, in the county of Erie and Sta-te of New York, have invented certain new and useful Improvements in Centrifugal Oilers, of which the following is a specication.

' `This invent-ion relates to a certain means for oiling a loose pulley, or for other similar purposes, by which the oil is forced onto the parts that require to be oiled by the combined action of centrifugal force and capillary attraction, all of which will be fully and clearly hereinafter shown by reference to the accompanying drawings, in which- Figure l is avertical central section through the complete device; also, a cross-section through the hub of the wheel or pulley to which it is attached, and through the shafting. Fig. 2 is a horizontal section on line X X, Fig. l. Fig. Bis a cross-section through line Z Z, Fig. b 4; and Fig. 4 is a side elevation of a portion ofthe body of the oiler, showing the openings through which the oil is carried by centrifugal force.

The oil-*cup a is preferably made of glass, so as to be transparent; but it may be of any other suitable material, and is a hollow vessel, substantiallyin the forni shown in Figs. l and 2; but any other suitable form may bensed. The lower tubular portion, a, is adapted to screw into a hub, a2, of a wheel or pulley, and is provided with a iianged portion, a3, having a circular or annular groove, at, provided with `any suitable packing, a5, adapted to receive the lower glass portion, b, of the cupa.

b represents the upper tubular portion having the openings b2, through which the oil is carried by centrifugal force. It is Valso provided with an annular groove, b3, having a `packing of rubber or other suitable material, 0*. This groove is adapted to receive the upper portion, b5, of the cup. rIlhe portion a is provided with a screw portion, c, adapted to` receive the part b, which is provided with a nut-section, c', by which it` may :receive a wrench to screw it in place. It is also provided with an internal screw, c2, by which the hollow stopper cgis secured in position. (See Fig. l.) Through the part ais a loosely-fitted ,5o

The operation of the invention is as follows:

Oil being put into the cup a and the pulley or wheel being made to revolve, the oil is thrown outward to the top e of the oiler, where it is forced in and closely around the rod c4, and from thence it is drawn down to the shaft by capillary attraction. When at rest and the oil-cup is in the position shown in Fig. l, the oil remains in the lower portion of the cup but when the pulley to which it is attached is in motion the oil is forced to the top of the cup, as above mentioned. y

In Fig. 1 I have shown a modied arrangement as an equivalent for the spring d for holding the rod c* to the shaft. It consists of the angular arm g2, jointed to the part b by a pin, g3. In this case the rod c4 should be made a little shorter, so that the portion i of the arm will rest upon it. g is a ball attached to said arm. It will now be seen that as the pulley revolves the ball will be thrown outward by centrifugal force from the center and cause the portion z' to force the rod c* downward against the shaft c5. The oil-vessel is formed so that the portions g project down as near to the shaft as possible, and thereby increase its capacity. Then a piston c and spring is used, the metal at the bottom of the opening can` be closed slightly, as shown at i', by a hammer, (or a tool made expressly for it,) so

as to prevent the piston from coming out when n the 4cap is removed for the purpose of relling. The form of the oil-cup is adapted to permit the centrifugal force to force all the oil to the piston oinrod c, from which it is taken by capillary attraction to the shaft, thereby insuring a continuous feed while thev pulley is in motion, and, being closed air-tight, there is no waste of the oil while the pulley is at rest. rIhe spring or counterweighted arm g2 is used to overcome the tendency of the centrifugal force to throw the rod c4 out and thereby hold it in Contact with the shaft.

I claiml. In an oil-cup, the tubular portion b', provided with the openings b2 near the center, in

combination with the rod c, asprng for holdl tially as specied, for holding said rod to the ing it down, and a pulley and shaft, substunshaft, and a hollow stopper, c", for the pur- Io tially as and for the purposes described. poses described.
